I need to replace the aquastat on my 1980 peerless boiler. The description is: Honeywell R8182D 1012. Everywhere I have looked, and all the people I have talked with say this unit never existed with the 1012 extension. When I ask for a replacement, they say I can not get a replacement without a crossreference to the 1012, which they say doesnt exist. This is a catch 22.
